    Open-Graded Friction Courses (OGFC) - CED Engineering

    Open-Graded Friction Courses (OGFC) Recent opengraded friction- -course pavements built in the U.S. and Europe have considerably higher air void contents than before (17 to 22%). The void content for hot mix asphalt (HMA) paving used in Tennessee is normally 4 to 7 percent. ewer OGFC mixes are muN ch more open with more voids.

    The major difference between macadams, other than aggregate size and pen grade, is whether they are classed as Open Graded or Close Graded (aka Dense). Open graded macadam is composed of aggregate with very little fines and may be permeable. It is a popular choice for hand-laid basecourses as it remains workable for longer at lower temperatures.
